There's always something special about seeing a build leave the workshop and start its new life on the road.

This shepherd's hut inspired van conversion recently made its debut event appearance and we think it looks right at home. Wishing the owners a successful season ahead!

Rolling out of the workshop and ready for service, this bespoke van conversion has been designed to capture the charm of a traditional shepherd's hut while delivering the practicality of a professional mobile catering setup.

Heading to its first stop over at Diddly Squat Farm Shop

Built around a unique rustic theme, the conversion features a real timber frontage complemented by a carefully matched wood-effect exterior wrap, creating the appearance of a handcrafted wooden hut while maintaining the durability and ease of maintenance required for commercial trading. Inside, the warm wood-effect finish continues throughout, creating an inviting atmosphere for both operators and customers.

The corrugated-style roof detailing, rustic cladding, traditional lighting, and natural finishes combine to create a distinctive countryside aesthetic that feels equally at home at food festivals, weddings, farm parks, breweries, country shows, and private events.

Purpose-built for high-quality grilled food service, this unit is equipped with:

✅ 4ft commercial griddle
✅ Commercial fryer
✅ Bain marie hot holding unit
✅ Undercounter refrigeration
✅ Drinks display fridge
✅ Stainless steel preparation areas
✅ Large serving hatch with customer shelf

The layout has been designed to comfortably handle burgers, loaded fries, breakfast menus, grilled sandwiches, hot dogs, wraps, and other popular street food offerings while maintaining an efficient workflow during busy trading periods.

This conversion combines rustic character with commercial practicality to create a memorable customer experience.

Thinking About Your Own Van Conversion?

Every business is different, which is why we build around your menu, workflow, and trading goals rather than offering a one-size-fits-all solution.

If you're planning a burger van, coffee unit, street food business, farm shop takeaway, or completely unique concept, we'd be happy to help bring it to life.

Getting a massive project like this Mercedes bus conversion right is all about the journey, and the evolution of this design was a brilliant collaborative process. We originally went through a few completely different exterior directions with the client,from leaving it with a clean bus aesthetic to cladding it out to match the look of their previous bus. Ideas were flowing back and forth until the client came to us with the concept of raw graffiti art. It was such a fun, creative idea that instantly brought out the natural character of the bus and guaranteed it would stand out even more.

While the artists transformed the exterior panels into the masterpiece you see, our engineering team faced some unique structural challenges up top. Incorporating a heavy-duty sign that combined a complex mix of traditional letter marquee lights, bright neons, and an actual working traffic light required some serious problem-solving to integrate seamlessly with the bus's roof structure. It took some precise fabrication and wiring adjustments, but we got there in the end without compromising on the sleekness or durability of the build.

This bus is going to be the absolute talk of any festival, weekend event, or public space it rolls into this summer. It is the ultimate proof of what happens when a client brings a bold vision to our workshop and we back it up with the technical engineering to make it a reality. We cannot wait to see this unit in full action out on the road.

If you have a unique vision for a van, truck, or bus conversion and want a team that can overcome the structural challenges to build it right, let’s get to work.

Posts like this are exactly why we love what we do. Seeing a trailer leave our workshop is one thing, but watching businesses like Yes Chef take it out into the real world and build something successful is what it's all about.

Congratulations on an incredible first year, and thank you for trusting A.R. Willis to be part of the journey. Here's to Year Two! 🍔🎉

It’s been a whole year since we picked up our brand new trailer, and what a year it’s been! 🎉

Look how the new one towers over the old unit, I often wonder how we managed the larger events with so little space 🤣🤣
In the last 12 months we’ve attended markets, festivals, private events, music festivals, dog shows, weddings, pop-ups and everything in between. We’ve met hundreds of customers, made new friends, worked some very long days, and created memories that will last a lifetime.

There have been early mornings, late nights, so many challenges along the way and plenty of hard work, but seeing the business continue to grow makes every minute worthwhile.

I’d like to express a huge thank you to everyone who has supported us, booked us, recommended us, shared our posts, and most importantly, bought food from us. Without you, none of this would be possible.

Here’s to another year of burgers, loaded fries, breakfast wraps, events, and hopefully even bigger things ahead! 🚚🍔

Thank you for being part of the yes chef journey 👨‍🍳

Not every food truck is built to blend in.

The Toastie Bus was designed to turn heads before a single sandwich leaves the grill.

Custom artwork. Bespoke fit-out. Professional kitchen. One seriously memorable street food setup.

From Just a Bus to the Ultimate Crowd-Pleaser: The Toastie Bus is Ready for the Road

If you want to completely dominate the food festival circuit, you don't just need great food, you need a presence that stops people dead in their tracks from across the field. That is exactly what this massive Mercedes bus conversion delivers. We took this vehicle from a simple yellow bus, and engineered it into a high-output mobile kitchen dedicated to serving up the ultimate grilled cheeses.

Every single inch of this build has been optimized for festival volume and serious visual impact. The exterior features incredible, vibrant graffiti art dripping with character, a massive custom "Toastie Bus" light setup mounted to the roof, and even a built-in traffic light. To maximize serving efficiency during peak rushes, our client gets to enjoy dual heavy-duty serving hatches with gas-strut openings, alongside an external slide-out grill station, allowing the chefs to keep orders flowing.

Step inside, and you will see the space is fully ready for its final equipment installs, the double griddles are perfect for high-volume toasting, and expansive prep counters. The workflow is mapped out perfectly so a full crew can pump out hundreds of gooey, perfect toasties an hour without getting in each other's way.

This build is just a sample of what we can do with a bespoke van, truck, or bus conversion. If you are ready to stop dreaming about expanding your food business and start building an asset that brings the crowds and seamless operation, let’s make it happen.

The UK street food market is growing at over 7% year on year, and new vendor entries have reached their highest level in more than a decade.

According to IBISWorld's 2025 industry report, that's good news for anyone already trading or planning to launch.

But it comes with a challenge.

More vendors on every pitch means customers have more choice. They're walking past multiple units before deciding where to spend their money. That decision often happens in seconds, and it starts with what your unit looks like, how it's laid out, and whether your service flow can handle busy trading periods.

A generic, off-the-shelf trailer may get you started, but it isn't designed around your menu, your brand, or the way you work. That can lead to compromises in workflow, customer experience, and operational efficiency.

For over 40 years, we've been building custom catering trailers for mobile food businesses across the UK. One thing we've seen time and time again is that traders who invest in a unit designed specifically around their operation often create a stronger customer experience, improve service efficiency, and build a more recognizable brand presence.

In a competitive market, your trailer is more than a kitchen. It's your shopfront, your workspace, and often the first impression customers have of your business.

Thinking about launching or upgrading your mobile food business? Start with the unit itself. A trailer designed around your menu, workflow, and brand can make a real difference to how efficiently you trade and how customers perceive your business. If you'd like to discuss your ideas, we're always happy to have a conversation.
